INTERLOCK SAFETY SYSTEM
The interlock modules function is to prevent the engine form starting if the blade and/or ground
speed lever are engaged. It also causes engine shutdown if the operator falls from, or attempts to
leave the operator position while the blades or ground speed lever are engaged. After the engine
starts, the operator must hold either the left or right O.P. lever down before engaging the blades or
moving the ground speed lever. If neither O.P. lever is held the engine will stop. Check the function
of the safety electrical system on a regular basis.
1. Engine must kill if blades are engaged without O.P. levers held down.
2. Engine must kill if ground speed lever is taken out of neutral without holding down O.P. levers.
3. Engine must not start unless blades are off and ground speed lever is in the neutral position.
4. Do not operate the mower if the interlock safety system allows operation or starting in any unsafe
condition.
